Following David’s prompt for spectra or AG Dra and SU Lyn…
It does seem a little more active but a bit of a bump/rise at 5250A down to 4300A compared to my last attempt – or is that a mistake? (or is it a drop at 5200A?). I might check my response curve freehand drawing!.
This seems to fit existing SU Lyn spectra quite well.
